Moka pot gasket size finder
Quickly find the right seal for your stove top espresso maker

Use this tool to find the correct gasket for your Bialetti, Alessi, or Grosche moka pot

Why we built the moka pot gasket size finder

While researching moka pots, we found that major brands like Bialetti and Alessi offer very little information about which gasket sizes fit which models.

A moka pot can last decades — but the gasket needs regular replacement.

We feared that people might be replacing perfectly good moka pots instead of buying new gaskets — because gasket size information is hard to find.

This tool exists to prevent landfill — and to save people hassle.

Where does the data for this tool come from?

The data for this tool come from scouring the Internet Archive, manufacturers’ websites, and manuals for moka pots. It was difficult to find, and not all the data is available.

There are a lot of moka pot brands — and life is short. So for now we’ve limited our research to moka pots by Bialetti and Alessi. We’ll be adding more in the future.

Moka pot gasket size tables

Use these tables to compare gasket diameters to see if your moka pot can use a gasket designed for a different moka pot. They are very simple and should be interchangable if they’re the correct size.
